  • Publication number: 20230391793
    Abstract: The present invention relates to a method of preparing an organosulfur compound, and more particularly, to a method of preparing an organosulfur compound including a step of synthesizing an organosulfur compound by reacting specific compounds with a metal hypohalite under a ruthenium catalyst in a mixed solvent containing water and an organic solvent, wherein reaction temperature during the synthesis is 0 to 25° C. According to the present invention, the present invention has an effect of providing an organosulfur compound preparation method capable of preparing an organosulfur compound in high yield due to excellent reaction stability, short reaction time, and reduced side reactions.

  • Publication number: 20140371432
    Abstract: The present invention provides a double-stranded RNA structure, which comprises a polymer compound covalently bonded to a double-helix oligo RNA useful for the treatment of diseases, particularly cancer, in order to enhance the delivery of the double-helix oligo RNA, and further comprises a target-specific ligand bonded thereto, a preparation method thereof, and a technique of delivering the double-helix oligo RNA in a target-specific manner using the RNA structure. A nanoparticle composed of the ligand-bonded double-helix oligo RNA structures can efficiently deliver the double-helix oligo RNA to a target, and thus can exhibit the activity of the double-helix oligo RNA even when the double-helix oligo RNA is administered at a relatively low concentration. Also, it can prevent the non-specific delivery of the double-helix oligo RNA into other organs and cells.
